radio technology for home remote control devices based on RF (radio frequency).
GreenPeak is a semiconductor company offering ultra low power wireless and
battery-free data communication technologies for sense and control applications
and was recently selected as 2009 Technology Pioneer by The World Economic
Contrary to traditional IR based remote controls, RF
remote controls provide two way high speed communication and do not require
line of sight as the signal goes through walls and floors. It is excellent for
controlling equipment inside a cabinet or in another room. With a nice stylish
flat screen on the wall, people do not want to have DVD-players or set-top
boxes within sight.
GreenPeak has developed a set of reference designs for
this new generation of RF remote controls (2.4 GHz, IEEE 802.15.4 compliant)
and RF modules for integration into hosts such as TVs, DVDs and set-top boxes.
These reference designs are based on GreenPeak's Emerald GP500C communication
controller, with dedicated features for the consumer electronics and remote
The Green Peak remotes enable the designer to develop an
ultra low power RF system with a much longer battery life. RF remote controls
equipped with GreenPeak's communication controller can be made maintenance
free: a single watch type battery can outlast the life time of the remote.
Remote controls designed with GreenPeak's communication
controller are based on the IEEE 802.15.4 industry standard for multiple
devices control. GreenPeak's solution also includes IR as secondary use for
legacy systems. This combo solution allows the use of a single universal remote
control for both IR and RF devices.
